What we checked

Six static checks, weighted by risk. Every result reflects only what could be observed in the published package and repository — never intent.

• Injection surface

  unscannable25% of grade

  Tool descriptions/manifest scanned for instruction-injection patterns (imperatives at the model, hidden text, 'ignore previous', data-exfil URLs).

  No tool descriptions, server instructions, prompts, or resources were fetched; nothing to scan for injection.

• Supply chain

  pass25% of grade

  Package provenance: namespace verification, repo linkage, maintainer count, account age, postinstall scripts, typosquat distance.

  Python build script has no build-time network/exec; repository linkage verified

• Credential hygiene

  warn15% of grade

  How the server takes secrets (env vs plaintext config vs hardcoded); secrets appearing in tool schemas.

  tests/test_observability.py: assigns a literal to secret (sens…ed (len 41)) — non-provider secret literal; prefer environment intake. tests/test_remote_asgi.py: assigns a literal to secret (do-n…en (len 32)) — non-provider secret literal; prefer environment intake.

• Permission scope

  warn15% of grade

  Declared tools vs. breadth (filesystem, network, exec); flags shell-exec and unbounded filesystem access.

  discloses broad/destructive filesystem access: src/mcp_trendpulse/news.py: open(…, 'w'/'a'/'x') write-mode file access Capability DISCLOSURE, not a verdict: static analysis sees the primitive is present and reachable, not whether its use is attacker-controlled.

• Version behavior

  fail10% of grade

  Diff of tool definitions between versions; new permissions or changed descriptions in a patch release (the postmark-mcp class).

  vs prior 0.2.10 (patch bump): new capability primitive(s) in source: fs-write; new hardcoded outbound host/BCC destination(s): 10.0.0.1, 127.0.0.1, 169.254.169.254, 172.16.0.1, 192.168.0.1, 224.0.0.1, 93.184.216.34, allowed.test, app.digestseo.com, clerk.example.test, digestseo.com, digestseo.example.test, evil.example.test, evil.test, example.com, github.com, img.com, issuer.example.test, mock.com, news.com, news.google.com, nytimes.com, staging.example.test, trendpulse.example.test, trends.com, user, www.google.com.

• Transport config

  warn10% of grade

  Remote servers: TLS and auth mode (none/token/OAuth). Local servers: whether the manifest indicates it phones home.

  manifest/source references telemetry behavior — disclosure
